BACKGROUND

1. Technical Field

The present disclosure relates to a composite connector and, particularly, to a composite connector for connecting a plurality of hard disks and a hard disk assembly using the same.

2. Description of the Related Art

A commonly used hard disk connecting mechanism is generally used for one hard disk only. However, if a plurality of hard disks are needed, the same number of hard disk connecting mechanisms are also needed, and each hard disk employs an electrical connector, a data connector and a plurality of cables for connecting with a motherboard of a computer, resulting in having a complex wire distribution, and is inconvenient for mounting or detachment.

Therefore, there is room for improvement within the art.

DETAILED DESCRIPTION

Referring to FIGS. 1 and 2, an exemplary embodiment of a hard disk assembly includes a hard disk connecting mechanism 100, a first hard disk 22 and a second hard disk 23. The hard disk connecting mechanism 100 includes a frame 20 and a cable connecting assembly 24. The first hard disk 22 and the second hard disk 23 may be a Serial Advanced Technology Attachment (SATA) hard disk or an Integrated Device Electronics (IDE) hard disk.

The frame 20 includes two fixing members 201 and a connecting member 203. Each fixing member 201 includes a longitudinal support portion 2011 and a fixing portion 2013 extending substantially perpendicularly from an end of the longitudinal support portion 2011. The connecting member 203 defines two fixing holes 2031 at each end thereof. Each support portion 2011 defines a plurality of guide holes 2014, which are spaced from each other, for fixing the first hard disk 22 and the second hard disk 23. Each fixing portion 2013 defines a threaded hole 2015 corresponding to the fixing hole 2031 of the connecting member 203. A screw (not labeled) threads through the threaded hole 2015 of each fixing member 201, and then engages in one of the fixing holes 2031, thereby fixing each fixing member 201 at each end of the connecting member 203.

The first hard disk 22 includes a main body 221 and a composite receptacle 223. The main body 221 defines a receiving slot 224 for receiving the composite receptacle 223. The composite receptacle 223 includes a power receptacle 2231 and a data receptacle 2233. The power receptacle 2231 and the data receptacle 2233 cooperatively define a slot 2235 therebetween. The main body 221 defines a plurality of threaded holes (not labeled) at each side for fixing the main body 221. Alternatively, the power receptacle 2231 may be integrally formed with the data receptacle 2233, and some of the pins of the composite receptacle 223 are capable of transmitting electrical power, and the other pins of the composite receptacle 223 are capable of transmitting data. The second hard disk 23 is similar to the first hard disk 21, and includes a main body 231 and a composite receptacle 233 received in the main body 231. The composite receptacle 233 includes a power receptacle 2331 and a data receptacle 2333. The power receptacle 2331 and the data receptacle 2333 define a slot 2335 therebetween.

Referring also to FIGS. 3 and 4, the cable connecting assembly 24 includes a composite connector 241, an electrical connector 243, two data connectors 244, four data cables 245 and five electrical cables 246. The composite connector 241 includes a longitudinal base 247, a first composite plug 248 corresponding to the composite receptacle 223 of the first hard disk 22 and a second composite plug 249 corresponding to the composite receptacle 233 of the second hard disk 23. The first composite plug 248 is formed at a side surface of the base 247; the second composite plug 249 is formed at the other side surface opposite to the first composite plug 248. The first composite plug 248 includes an electrical plug 2481 and a data plug 2483 adjacent to the electrical plug 2481. The electrical plug 2481 includes five conductive pins (not labeled) for being connected to the electrical cable 246; the data plug 2483 includes a plurality of data pins (not labeled) for being connected to the data cable 245. In the illustrated embodiment, the electrical plug 2481 is integrally formed with the data plug 2483, and is divided by a partition portion 2485. When the first composite plug 248 engages with the composite receptacle 223, the partition portion 2485 is latched in the slot 2235, to prevent the relative movement of the first composite plug 248 and the composite receptacle 223. The second composite plug 249 is similar to the first composite plug 248, and includes an electrical plug 2491, a data plug 2493 and a partition portion 2495 between the electrical plug 2491 and the data plug 2493. The base 247 defines five wire holes 2471 for the electrical cables 246 to pass through the middle and two through holes 2473 at each side of the wire holes 2471 for the data cables 245 to pass through. One end of each electrical cable 246 is passed through the wire hole 2471, and is connected to the conductive pin of the electrical plug 2481 of the first composite plug 248 or the second composite plug 249; the other end of the electrical cable 246 is connected to the electrical connector 243. One end of the data cable 245 is passed through the through hole 2473, and is connected to the data pin of the data plug 2483 of the first composite plug 248 or the data plug 2493 of the second composite plug 249; the other end of the data cable 245 is connected to the data connector 244.

In assembly, the first hard disk 22 is positioned between the two fixing members 201, and adjoined to the connecting member 203. A screw passes through the guide hole 2014 of the fixing member 201, and engages in the threaded hole of the main body 221, to fix the first hard disk 22 in the frame 20. The first composite plug 248 is inserted into the receiving slot 224, the electrical plug 2481 engages with the power receptacle 2231 of the first hard disk 22, and the data plug 2483 engages with the data receptacle 2233 of the first hard disk 22. The partition portion 2485 of the first composite plug 248 is latched in the slot 2235, to prevent the relative movement of the first composite plug 248 and the composite receptacle 223. The second hard disk 23 is inserted between the two fixing members 201, and the second composite plug 249 engages with the composite receptacle 233 of the second hard disk 23 in the same manner as the first composite plug 248. Then the second hard disk 23 is also fixed on the frame 20 by the screws. The electrical connector 243 and the data connector 244 may be connected to a motherboard of a computer, and data may be transmitted between the motherboard and the first and second hard disks 22 and 23 via the data cables.

The composite connector 241 includes the first composite plug 248 for connecting with the first hard disk 22 and the second composite plug 249 for connecting with the second hard disk 23, respectively; thus the first hard disk 22 and the second hard disk 23 can be mounted together on the frame 20. The cables connected to the first hard disk 22 and the second hard disk 23 may be simplified, for the sake of more convenient mountability or detachment.

It is understood that the number of composite plugs 248 and 249 may be changed according to the number of hard disks 22 and 23. That is, if a third hard disk is needed, the composite connector 241 may further include a third composite plug (not shown) for engaging with the third hard disk; if more hard disks are needed, more composite plugs would be added accordingly.

Finally, while particular embodiments have been described, the description is illustrative and is not to be construed as limiting. For example, various modifications can be made to the embodiments by those of ordinary skill in the art without departing from the true spirit and scope of the invention as defined by the appended claims.
